Device and Method for Bonding Sensor to Display Panel

2. The device of claim 1, further comprising an adhesive injector for applying an adhesive that comprises a curable resin over at least one of the front surface of the fingerprint sensing unit and the rear surface of the display panel.

4. The device of claim 1, wherein the first planar surface having the (1-1)-th inclination and the second planar surface having the (2-1)-th inclination are parallel to each other.

7. The device of claim 6, wherein the controller determines at least one of the (1-2)-th inclination and the (2-2)-th inclination that allows the first gap and the third gap to be substantially equal to each other and the second gap and the fourth gap to be substantially equal to each other, based on a difference between the first gap, the second gap, the third gap, and the fourth gap.

12. The device of claim 11, wherein the controller determines at least one of the (1-2)-th inclination and the (2-2)-th inclination that allows parallelism of the front surface of the fingerprint sensing unit to be substantially minimum with respect to the second planar surface.

17. The picker of claim 15, wherein a step difference between the first surface and the second surface is substantially equal to or less than a thickness of the flexible printed circuit board.

18. The picker of claim 15, wherein the second surface comprises a material substantially the same as that forming the first surface, or a material having elasticity.
